testlib: allow more argument to mkcommit
This is simple and handy. See next changesets for usage.

The sentence is now correct.

contrib: add new examples area and start it out with a config for `hg fix`
This is the configuration contributors should use for our C/C++
code. I expect to expand this file as we get more automated formatter
oversight.

transaction: detect an attempt to truncate-to-extend on playback, raise error
On some networked filesystems, writes can have delayed finalization/confirmation
and write races can occur such that a remote modification will "win" and
modifications will be lost. There is no functionality for providing this
feedback to userspace programs (in fact, there's not even functionality for
providing this information to the Linux kernel...), so these programs may see
the files suddenly change.
We've noticed that there have been cases where Mercurial has detected something
has gone wrong and attempts to abort (rolling back the transaction), which is
good. However, when rolling back the transaction, for the append-only files,
we attempt to "truncate" the file back to the size it was in before the hg
transaction started, but end up *extending* it. This may be harmless, but if
this happens to the 00changelog.i file, we get a bunch of nulls on the end of
the file and this causes hg to become *really* confused. :)
If we detect that some modification of the file outside of this Mercurial
process has caused the file to be smaller than the size we are attempting to
truncate to, let's just exit and stop trying to clean up the repository -
continuing will likely just cause more damage.

osutil: tolerate Py_GetArgcArgv not being set up properly

osutil: allow disabling setprocname via a define passed to the compiler
In some situations, we run a custom python launcher that appears to not set up
Py_GetArgcArgv correctly. We then proceed to promptly crash when we attempt to
dereference NULL. Being able to completely disable setprocname is beneficial in
these situations, since we won't even attempt to use it, even if the case that
causes the crash is fixed.
Right now, if I compile osutil.so with -DSETPROCNAME_USE_NONE, the compilation
fails on python3 due to SETPROCNAME_USE_NONE redefinition. I could possibly
work around that, but it's likely helpful to have a way of disabling this
completely without it being brittle (i.e. if python3 ever gains the ability to
perform this operation).

stack: use repo.revs() instead of revsetlang.formatspec() + scmutil.revrange()
Using scmutil.revrange() it's possible to use multiple revsets at the same
time, but we're not using that functionality in stack.
I thought maybe that function could be used to make stack definition
customizable (by combining various parts into one set), but scmutil.revrange()
gives the union of all provided revsets, which is not very useful in stack's
case (we want "and" between parts, not "or").
